Title: Detecting circuit of phase inversion
Inventor: KOSEKI TOSHIICHI
IPC: H04L27/22
Filed: 1983-10-18
Abstract: PURPOSE:To obtain stably a phase inverted pulse with no regulation by using a BPF which passes a fixed frequency at its pass band and an envelope detecting circuit which detects the envelope of an AC output signal of said BPF. CONSTITUTION:When a signal inverted in phase is supplied to a terminal (a), a waveform having an amplitude reduced at a phase inverting part appears at an output terminal (d) of a BPF8. This waveform is detected by a wave detecting circuit 20 containing diodes 10 and 11 to obtain a signal having a waveform of only the negative side. Furthermore, envelope components are extracted through an LPF21 comprising an inductance 13 and a capacitor 14. Then the waveform of said signal is shaped by a waveform shaping circuit 22 comprising resistances 15 and 17 and a transistor 18. Thus a phase inverted pulse is obtained at a terminal (f).

Title: Prediction encoder
Inventor: KAGA KENJI
IPC: H03M7/38
Filed: 1988-08-04
Abstract: PURPOSE:To set the division of a '0' code in the run length code of a prediction result at minimum by adding the identification code of a predictor to the prediction result, adding the identification code concerned only when the predictor has changed and adding '0' except for said case. CONSTITUTION:When the number of the predictors 101A, 101B... to be integrated is increased, several bits of the identification codes 108 are required. When the identification codes are added in the forms as they are, the prediction result, namely, the '0' code of the run length code is divided, and that an encoding efficiency is deteriorated comes into question. Thus, the identification code concerned 108 is added only when the predictors 101A and 101B... have changed, and '0' is added except for said case. Thus, the division of the '0' code in the run length code can be held at minimum and the encoding efficiency as a whole can be improved.

Title: Production of urea
Inventor: IKARIYA TAKAO
IPC: B01J31/00
Filed: 1985-09-04
Abstract: PURPOSE:To obtain urea in high recovery of a catalyst and in high yield, by reacting an aromatic primary amine with an aromatic nitro compound and carbon monoxide in the presence of a catalyst consisting essentially of a platinum group metal-containing compound. CONSTITUTION:An aromatic primary amine (e.g., aniline) is reacted with an aromatic nitro compound (e.g., nitrobenzene) by the use of a catalyst consisting essentially of a platinum group-containing compound [e.g., Ru3(CO)12] to give the aimed urea. The urea has low solubility insolvents or in aromatic amines and nitro compounds. Therefor, the formed urea is precipitated as crystal only by cooling the solution after the reaction to about room temperature, the solution is filtered to efficiently give the urea as a solid substance. On the other hand, since the catalyst has been dissolved in the filtrate, it is directly usable economically. The side reactions are few and the urea can be obtained in high yield.

Abstract: PURPOSE:To prevent a trouble from being generated when an operator forgets to perform a setting operation, by detecting the thickness of a paper and automatically adjusting the gap between a printing head and a platen. CONSTITUTION:In setting printing paper, the paper is passed through a paper thickness sensor 5, whereby a voltage corresponding to the thickness of the paper is generated, the voltage is inputted to an amplifier 6, and an output from the amplifier is inputted to an A-D converter 7. A microcomputer 8 takes three samples of digital value of the paper thickness, and takes as average of the three values to determine the paper thickness. Next, prestored stepping motor driving information corresponding to the paper thickness is read, and is sent to a stepping motor 9 as a driving pulse. The stepping motor 9 thus supplied with the driving pulse generates a torque, which is transmitted to a cam 3 to drive a base for a printing head 1. By this, the position of the printing head, namely, the gap between the printing head and a platen is adjusted to an appropiate value, so that to trouble is generated when an operator forgets to set an adjusting lever.

Abstract: PURPOSE: To change the pulse number of supply fluid pressure and to stabilize fluid pressure by providing an upstream channel by which the pressure fluid is supplied to a plunger and a downstream channel by which the pressure fluid is discharged, and increasing/decreasing the throttling amount of a throttling device arranged in the downstream channel. CONSTITUTION: When a lower moving contact point 40 is brought in contact with a lower fixed contact point 42, a controller 14 operates an opening/closing valve 10 so that pressure fluid is supplied to an actuator 1 and a fluid pressure digital controller 15, the pressure fluid is delivered from an upstream channel 34 to a hole 17, a plunger 18 is lifted, the lower moving contact point 40 and the lower fixed contact point 42 are disconnected from each other so as to stop pressure fluid supply, and fluid is discharged from a downstream channel 35 so as to lower the plunger 18. When this operation is repeated, the plunger 18 and the fluid pressure are vibrated.  This vibration period is shortened if the throttling amount of a throttling device 27 is increased so as to increase an exhaust amount so that the pulse number of the fluid pressure is increased, and the pulse number is reduced if the throttling amount is reduced so as to decrease the exhaust amount, therefore, the pulse number of the fluid pressure to be supplied can be changed.

IPC: B60C11/12
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of displaying high performance on the ice without deteriorating other performances. SOLUTION: A plurality of narrow grooves 22 with a rectangular cross section are formed inclined at a fixed angle in a siping side wall face 20A of sipes. Even if the sipes are closed when a load is acted on a tire, since the section in which the narrow grooves 22 are formed do not contact with the ice road face, the water 26 on the ice road face 24 can be absorbed and removed by the narrow grooves 22. Since the narrow grooves 22 wherein one side opens facing a tread section 18A and the other side opens facing a side face 18B can discharge the absorbed water out of a block 18 in order, the water 26 on the iced road face 24 can be further discharged. Since the water can be discharged without using sipes much, avoiding the deterioration of block rigidity due to much use of sipes.
